* MAINT: .gitignore += generated umath/loops.hKirill Smelkov2014-07-271-1/+1
| | | | | | | | | Commit 494abcf1 (ENH: speed-up minimum, maximum and xor for bool dtype) reworked numpy/core/src/umath/loops.h to be autogenerated at build time, but forgot to update .gitignore. Fix it, so that the now-autogenerated loops.h do not constantly show as untracked in git status output.

|/ / | | | | | | | | | | | | | | | | | | When `x` has more than one element the condlist `[True, False]` is being made equivalent to `[[True, False]]`, which is correct. However, when `x` is zero dimensional the expected condlist is `[[True], [False]]`: this commit addresses the issue. Besides, the documentation stated that there could be undefined values but actually these are 0 by default: using `nan` would be desirable, but for the moment the docs were corrected. Closes #331.

| * | BUG: Correct behavior for lists of tuples in unique, closes #4785jaimefrio2014-06-062-7/+11
|/ / | | | | | | | | | | | | | | np.unique produces wrong results when passed a list of tuples and no keyword arguments, as it fails to recognize it as a multidim array, but handles it as a 1D array of objects. The only way around this seems to be to completely eliminate the fast path for non-array inputs using `set`.

| * | ENH: rewrite ma.median to improve poor performance for multiple dimensionsJulian Taylor2014-06-022-16/+38
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | many masked median along a small dimension is extremely slow due to the usage of apply_along_axis which iterates fully in python. The unmasked median is about 1000x faster. Work around this issue by using indexing to select the median element instead of apply_along_axis. Further improvements are possible, e.g. using the current np.nanmedian approach for masked medians along large dimensions so partition is used instead of sort or to extend partition to allow broadcasting over multiple elements. Closes gh-4683.
| * | ENH: use sparse meshgrid instead of indices().tolist()Julian Taylor2014-06-021-5/+6
| | | | | | | | | | | | | | | | | | | | | | | | tolist() converts numpy integers to python integers which are converted back to numpy integers by the indexing. meshgrid(indexing='ij') returns the indices wanted here as the right type. triples performance of sorting a size=(200, 200, 50) array along axis 2 and reduces memory usage by almost 40%.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The new format only increases the header length field to 4 bytes. allows storing structured arrays with a large number of named columns. The dtype serialization for these can exceed the 2 byte header length field required by the 1.0 format. The generic functions automatically use the 2.0 format if the to be stored data requires it. To avoid unintentional incompatibilies a UserWarning is emitted when this happens. If the format is not required the more compatible 1.0 format is used. Closes gh-4690
